A highly selective ratiometric fluorescent pH probe based on a PAMAM wavelength-shifting bichromophoric system

A review on comparative study of PPI and PAMAM dendrimers

“…Lower generations of PPI dendrimers like 0.0, 1.0 and 2.0G have open structure and showed high polarity range (Shah et al 2011;Winnicka et al 2009). In case of PAMAM dendrimers, many large number of internal pockets are available (Alamry et al 2015;Aldosari 2011). PAMAM has tertiary amine, amido groups and alkyl chain and is polar in nature, whereas PPI dendrimers is non-polar in nature, i.e., contains alkyl chain and tertiary group.…”

“…Both PPI and PAMAM dendrimers have cationic surface groups. PAMAM dendrimers also show pH-sensitive drug release at acidic pH due to protonation of amine groups Shape Spherical shape (Mishra 2011) Globular shape, gives the larger surface area which is ornamental with chromosphere groups, and results in increasing the absorption (Alamry et al 2015) Toxicity Toxicity depends upon the number of amino groups (Marvaniya et al 2010) Shows dose-dependent toxicity (Kesharwani et al 2014a)…”

Novel nanosized water soluble fluorescent micelles with embedded perylene diimide fluorophores for potential biomedical applications: Cell permeability, localization and cytotoxicity

“…The PET process can be removed after protonation of the electron donating amine in acid media [45][46][47][48][49][50], which was the reason to record the fluorescence of PDI 2 in DMF solution containing 1 × 10 − 5 mol L − 1 HCl. In acid DMF solution the PDI 2 showed typical spectrum for perylene tetracarboxydiimide fluorescence with three narrow bands at 546, 586 and 640 nm (Fig.…”

Synthesis, spectral properties and antimicrobial activity of a new cationic water‐soluble pH‐dependent poly(propylene imine) dendrimer modified with 1,8‐naphthalimides

“…[5] These dendrimers react to a change in fluorescence intensity when the pH of the medium changes, making them highly sensitive pH sensors. [12][13][14][15] Because the monomeric 1,8-naphthalimide compounds also exhibit biological activity, we have studied the antimicrobial and anticancer activity of PAMAM and PPI dendrimers and their metal complexes modified with 1,8-naphthalimides. [16][17][18][19][20][21] The deposition of such bioactive dendrimers on the surface of textile materials creates textiles with high antimicrobial activity and results in better control of biofilm formation.…”
